Description générale

NMC811, electrode sheet, aluminum substrate, is a ready-to-use cathode for lithium-ion battery research. NMC811 is a quaternary lithium metal oxide, with the formula LiNi0.8Mn0.1Co0.1O2, and is a state-of-the-art cathode material for lithium-ion batteries that offers high energy density and cycle lifetimes. The composition of our cathode film is 90% active material, 5% PVDF binder, 5% carbon black.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency. Click here for more information.

Application

The main application of our NMC811 electrode sheet is as a cathode for next-generation lithium-ion batteries (LIBs). The 811 refers to the ratio of metals in the active material that combine to give the high performance: nickel provides high energy density while the manganese and cobalt help to stabilize the spinel crystal structure to extend the cycle lifetime at moderate-high operating temperatures. NMC811 (LiNi0.8Mn0.1Co0.1O2) is a highly nickel-rich NMC composition that is currently attracting considerable attention as a cathode material because it can deliver a high specific capacity of ~200 mAh g–1 with a high average discharge potential of ~3.75 V vs Li/Li+, resulting in a substantial increase of ~25% in energy density compared to LiCoO2.
